Abstract

An image scaling system for converting a sampling rate of an input video signal comprising input pixel data to produce a magnified or reduced output video image comprising output pixel data includes a first one-dimensional image sealer comprising a single-stage finite-duration impulse response (FIR) filter structure with poly-phase filter responses that receives and scales the input pixel data by a scaling factor in either a horizontal or vertical direction to produce output pixel data and a second onedimensional image sealer comprising a single-stage FIR filter structure that is coupled in tandem to the first one-dimensional image sealer and scales by the scaling factor the output pixel data from the first one-dimensional image sealer in a direction perpendicular to that of the first one-dimensional image sealer to produce the magnified or reduced output video image.
